The JSW Difference
Our solution eliminates the need for you to purchase equipment, hire specialized operators, or develop welding procedures. You receive a completed pipeline with documented weld quality at a predictable per-joint cost.
Our testing across multiple pipeline projects confirms: Automated welding systems maintained consistent weld quality even when operator shift changes occurred, eliminating the fatigue factor that affects manual welding.
Automated Welding Technologies Deployed by JSW
JSW deploys four automated welding technologies based on your project requirements, pipe diameter, wall thickness, and terrain conditions.
Orbital Welding Systems for Precision Applications
JSW’s orbital welding services rotate the welding torch 360 degrees around stationary pipe, making them ideal for pipe-to-pipe joints in long-distance construction. We deploy orbital welding for:
Long-distance transmission pipelines (oil, gas, water, air)
Refinery and petrochemical facility piping
Power plant steam and cooling water systems
Confined space applications where manual access is limited
Typical diameter range: 2 inches (50 mm) to 56 inches (1,422 mm)
Dual-Torque Automatic Welding for High Production
Our dual-torque automatic welding service uses two welding torches operating simultaneously. The leading torch performs the primary weld while the trailing torch provides additional fill or cap passes. This configuration reduces total welding time per joint by up to 40% compared to single-torch systems.
Best suited for: Large-diameter pipelines, thick-wall pipe (up to 50 mm), projects with tight delivery schedules
Pulsed MIG Automatic Welding for High-Strength Steels
JSW’s pulsed MIG automatic welding service modulates welding current between low background and high peak current, creating controlled spray transfer with minimal spatter. This technology is particularly valuable for:
Root passes requiring precise penetration control
Overhead and vertical welding positions
High-strength steel grades (X70, X80, X100)
Projects requiring controlled cooling rates to prevent hydrogen-induced cracking
Friction Stir Welding for Specialty Applications
Friction stir welding (FSW) is a solid-state joining process that creates welds without melting the base material. While less common for mainline pipeline welding, JSW deploys FSW for:
Aluminum pipeline construction
Clad pipe joining where metallurgical compatibility is critical
Weld repair applications (friction stir plug welding)
Pipeline modification requiring minimal thermal distortion

How JSW Integrates Automated Welding with Other Pipeline Services
Automated welding is rarely an isolated service. JSW combines automated welding with our full suite of pipeline solutions to provide end-to-end support for oil, gas, water, and air pipeline projects.
Pipeline Construction + Automated Welding
For new pipeline construction projects, JSW provides both automated welding services and complete pipeline construction management, including trenching, stringing, bending, coating, and backfilling.
Hot Tapping and Pipeline Plug Services
When operating pipelines require branch connections or isolation, JSW performs hot tapping and pipeline plug services. Our automated welding capabilities ensure that branch connection welds meet the same quality standards as mainline welds, even under pressure.
Common scenario: A client needs to add a new delivery point to an existing 24-inch natural gas pipeline. JSW performs hot tapping to create the branch connection, followed by automated welding for the branch fitting attachment.
Pipeline Stopple and Pipeline Stopper Installation
For pipeline modification or repair requiring flow isolation, JSW provides pipeline stopple and pipeline stopper installation. The temporary bypass lines required for stopple operations are fabricated using our automated welding systems to ensure leak-free performance.
Pipeline Tapping Services
JSW’s pipeline tapping services create access points into existing pipelines without interrupting flow. The tapping fittings are welded using automated processes to maintain integrity under operating pressure.
Trenchless Pipe Rehabilitation
For pipelines that cannot be excavated, JSW offers trenchless pipe rehabilitation including cured-in-place pipe (CIPP), slip lining, and close-fit lining. While these methods reduce the need for extensive welding, any access fittings or connections still require automated welding for quality assurance.
Pipeline Maintenance and Restoration
JSW provides ongoing pipeline maintenance and restoration services for aging infrastructure. Our automated welding systems are deployed for:
Weld repair of corrosion-damaged areas (friction stir plug welding)
Sleeve and wrap installation for mechanical reinforcement
Full section replacement using automated orbital welding
Pipeline modification to accommodate new routing or flow requirements
